[C++-sig] vc++ assertion error upon runtime

[hitesh dhiman]

Hi Jim,
Well, the code's rather official, so i won't be able to give the exact
details, but here's the code simplified:

CFunctionRequest( pData, (DWORD*)&ucmmReq.len)
 where pData is BYTE    pData[512];
and
 typedef struct
{
int len;
char* data;
} Data;
with Data    ucmmReq

The definition for the CFunctionRequest is CFunctionRequest(BYTE* pRequest,
DWORD* pLength)
This is where the problem occurs. Above this, it works fine.
Do let me know if some more info is needed.
Thanks.
